{But now} (
uni de). In the new condition. {Wherein we were
holden} (en h(9369) kateichometha). Imperfect passive of katech(935c),
picture of our former state (same verb in  1:18 ). {In newness of
spirit} (en kainot(8874)i pneumatos). The death to the letter of
the law (the old husband) has set us free to the new life in
Christ. So Paul has shown again the obligation on us to live for
Christ.
